This patch to libgo makes the testsuite generate a libgo.sum and
libgo.log file which are much like the ones that DejaGNU would generate.
My hope is that this will cause the various scripts we have that parse
DejaGNU files do something useful with the libgo test results.
Bootstrapped and ran Go testsuite on x86_64-unknown-linux-gnu.
Committed to mainline.
